The pigeon-eating Lesser Black-Backed Gull was finishing off his latest victim on the Long Water near the Italian Garden, the first time I have seen him here.
But when I got to the far end of the Serpentine he had flown there before me, and was in his usual place near the Dell restaurant with his mate. He was still hungry (or maybe she was) and came ashore in a low, surreptitious posture before running at a group of pigeons.
But the pigeons in this area know what he's up to, and escaped in good time.
There is yet another brood of Moorhen chicks in the Italian Garden. It's hard to keep track of the two pairs here, but I think that each has had three broods now, and several surviving chicks of various sizes are roaming around the ponds. Here is one of the new chicks in the nest with an unhatched egg.
The Great Crested Grebe family from the nest near the bridge were having a moment of peace in the shade of the willow tree.
The Black Swan passed in front of the tree, going under the bridge to look for the adopted cygnet.
This was just the other side of the bridge, staring vaguely at a Coot which didn't like anyone getting too near its chick. The two swans wandered off together.
The Tufted duckling was seen this morning near the reed bed east of the Lido. But when I got there, mother and duckling had retreated to the island. I couldn't get an unobstructed view of them.
A flock of Mistle Thrushes flew into the rowan trees on Buck Hill for a meal of berries. They never stay in these trees for long. They cram themselves quickly with berries and then fly off to a taller and safer tree to digest them.
The pair of Coal Tits near the bridge came out to be fed. When photographing one of them I accidentally caught my own reflection in its eye.
One of the Little owlets near the Albert Memorial flew into an oak tree and tried to land next to its father, shown here.
There was a brief flurry and the owlet was sent packing. It landed in a horse chestnut, looking cross.
The female of the pair near the leaf yard was on her favourite branch in the chestnut tree just uphill from the nest tree.
L. Fairfax, who often comments on this blog, found the nest of a solitary wasp, Astata boops, beside a path near the Albert Memorial and sent me this excellent picture. (Boops rhymes with 'Co-ops', not with 'oops'.)
This picture by David Element wasn't taken in the park, but is too good not to use. A female Southern Hawker dragonfly mistook his leg for a tree and laid some eggs on it.
